Perhaps we ought to determine the merits or demerits of a vehicle like the Hummer according to the things it does to all of us rather than the things it does for those who drive them. With fuel efficiency somewhere around 11 miles to the gallon, use of the Hummer H2 makes us more dependent on oil, which, in turn, makes us more likely to go to war in oil-rich areas of the world. Even if we can forget that the world's oil resources are limited and, if we continue consuming gasoline the way we consume it, bound to run out before we have developed alternative fuels and transportation methods, we ought to remember that consumption of fossil fuels adds to ozone pollution and pumps more carbon dioxide into our already warming atmosphere. If we consider, too, that Hummer drivers use them pretty much the same as other drivers use their vehicles--that is, drivers alone in their vehicles--we ought to realize that very few drivers have legitimate reasons to drive Hummers or other vehicular behemoths; they drive them simply because they want to drive them. Driving such environmentally and socially destructive vehicles may well be our right, but we exercise that right at the expense of our responsibility to preserve our environment and our social order for future generations. I would not want to prevent people who legitimately need them from driving them, but I'd like those who do not need such large, inefficient vehicles to stop destroying our future.
